SPECIFICATION forming part of Letters Patent No. 767,158, dated August9, 1904.

Application filed February 1, 1904- Serial No. 191,419. (No modeLl Toall whom it ntay concern:

, mass, together with steam and hot-air heating appliance to thoroughlydry the grain as it is being conveyed through the several compartmentsof the drying-chamber.

My invention will be more fully understood by reference to theaccompanying page of drawings, in which Figure 1 illustrates a sideelevation of my drier, together with the heating appliances I desire toemploy for the purpose of drying the grain; and Fig. 2 is a verticalsection of the drier, taken on a line 2 2 of Fig. 1.

Referring to the reference-letters indicated throughout the drawings, Arepresents the drying-chamber, which in the present instance is dividedinto three communicating compartments A, A and A the first compartment Aof which is provided at one end with an inlet-chute a and at theopposite end with a discharge-opening a, leading into the compartment Amanner provided with an oppositely-disposed discharge-opening a leadinginto the compartment A, which has a discharge-chute a leading to anysuitable receptacle placed to receive the finished product. Thecompartment A is provided with a central shaft B, controlled in itsrotation by means of fast and loose pulleys B and B and having agitatorsor paddles B to agitate the grain. The compartment A is provided with asteam-drum O, surrounded by a steam-coil C, the former being suppliedfrom a steam-inlet connection 0 and a discharge connection 0, while thelatter is at its opposite ends in open communica- This compartment is inlike tion with the steam-drum. The drum 0 is also provided with a numberof inclined blades 0 which in conjunction with the coil tend to feed thegrain toward the opening (K.

In the compartment A is contained a steamdrum D, in all respects likethat of the compartment A having a steam-coil (Z surrounding it and inopen communication therewith, the drum being supplied by a steamconnection 01 and having a discharge connection (Z This drum is alsoprovided. with paddles, which are marked (P, which, together with thecoil, tend to feed the material contained in the compartment toward thedischarge-chuterf.

The drums G and D are caused to rotate by means of a train of gearingoperated from the shaft B, said shaft being provided with a gear E,meshing with an idler E, from which power is transmitted to a gear E onthe connection c and from thence to an idler E which drives a gear E,mounted on the connection cZ.

Steam is supplied to the drums C and D from a boiler or steam-generatorF through a pipe f, which connects with a stuffing-box f on theconnection 0, and from thence by a branch f to a stufling-box f mountedupon the connection d. In addition to the use of the steam-heatingappliances just described my invention contemplates the introduction ofhot air to the grain as it is being fed through the drier, and in thisconnection I prefer to utilize the products of combustion from thefurnace of the boiler F after the fire has attained a high degree ofincandescence.

The boiler F is provided with the conventional stack F, in which I placea damper F and below the damper a branch pipe F leading to a rotary pumpG.

From the pump G a number of branches 9, g, and lead to the compartmentsof the drier, the first communicating directly with the compartment Aand the remaining branches extending into the respective compartments Aand A and having downwardly-projecting nozzles 9 supplying heated airand gases to the grain as it is being agitated. The heated air and gasesdischarged through the nozzle g pass through the several compartments ofthe drier and out through a stack H, the discharge from which may beregulated by a damper H.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

1. A drier comprising a receptacle to receive waste brewers grains,divided into a number of compartments, a steam-generator located inclose proximity to said drier, a pipe leading from the furnace of saidsteam-generator to the compartments of the drier, a pump in line ofconnection with said pipe, agitating devices in each of the compartmentsof said drier and a steam connection from the generator to the drier toheat one or more of the agitators, substantially as specified.

2. A drier comprising a receptacle divided into a series ofcommunicating compartments, a steam and hot-air generator, a pipeleading from the furnace of the generator to the drier, means forforcing heated air and gases through said pipe, agitating devices ineach of the compartments and a pipe leading from the boiler of thegenerator to the agitators, substantially as described.

3. A drier comprising a receptacle divided into a series of superposedcommunicating compartments, agitating devices located in each of saidcompartments, means for operating the same, a generator located in closeproximity to the drier, a line of pipe interposed between the boiler ofthe generator and the agitating devices, a line of pipe interposedbetween the furnace of the generator and each of the compartments of thedrier, and a pump in line with said pipe, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

AMAND LEYER.
